Place in the Patriarchal Line
Serug occupies a fixed position in the post-Flood genealogy of Genesis 11, between Peleg's son Reu before him and his own descendants Nahor and Terah after him, the line continuing to Abraham. Because the Gospel of Luke traces the ancestry of Christ back through this same sequence, Serug is counted among the forefathers of the Lord according to the flesh, which is the ground of his liturgical commemoration alongside the other patriarchs of the period.
